Eliminates a block of comments that describe how routing table updates
are to be handled. These comments no longer apply following the removal
of TIPC's prototype multi-cluster support.
Note that these changes are essentially cosmetic in nature, and have
no impact on the actual operation of TIPC.

This "shortform" is actually longer than typing out what it is really
trying to do, and just makes reading the code more difficult, so
lets simply shoot it in the head.
In the case of log.c - the comparison is on a u32, so we can drop the
check for < 0 at the same time.

Adds a new check to TIPC's name table logic to reject any attempt to
create a new name publication that is identical to an existing one.
(Such an attempt will never happen under normal circumstances, but
could arise if another network node malfunctions and issues a duplicate
name publication message.)

Streamlines the logic that prevents an application from binding a
reserved TIPC name type to a port by moving the check to the code
that handles a socket bind() operation. This allows internal TIPC
subsystems to bind a reserved name without having to set an atomic
flag to gain permission to use such a name. (This simplification is
now possible due to the elimination of support for TIPC's native API.)

Eliminates a check in the processing of TIPC messages arriving from
off node that ensures the message is destined for this node, since this
check duplicates an earlier check. (The check would be necessary if TIPC
needed to be able to route incoming messages to another node, but the
elimination of multi-cluster support means that this never happens and
all incoming messages are consumed by the receiving node.)
Note: This change involves the elimination of a single "if" statement
with a large "then" clause; consequently, a significant number of lines
end up getting re-indented. In addition, a simple message header access
routine that is no longer referenced is eliminated. However, the only
functional change is the elimination of the single check described above.

Utilizes the new "node signature" field in neighbor discovery messages
to ensure that all links TIPC associates with a given <Z.C.N> network
address belong to the same neighboring node. (Previously, TIPC could not
tell if link setup requests arriving on different interfaces were from
the same node or from two different nodes that has mistakenly been assigned
the same network address.)
The revised algorithm for detecting a duplicate node considers both the
node signature and the network interface adddress specified in a request
message when deciding how to respond to a link setup request. This prevents
false alarms that might otherwise arise during normal network operation
under the following scenarios:
a) A neighboring node reboots. (The node's signature changes, but the
network interface address remains unchanged.)
b) A neighboring node's network interface is replaced. (The node's signature
remains unchanged, but the network interface address changes.)
c) A neighboring node is completely replaced. (The node's signature and
network interface address both change.)
The algorithm also handles cases in which a node reboots and re-establishes
its links to TIPC (or begins re-establishing those links) before TIPC
detects that it is using a new node signature. In such cases of "delayed
rediscovery" TIPC simply accepts the new signature without disrupting
communication that is already underway over the links.

Adds support for the new "node signature" in neighbor discovery messages,
which is a 16 bit identifier chosen randomly when TIPC is initialized.
This field makes it possible for nodes receiving a neighbor discovery
message to detect if multiple neighboring nodes are using the same network
address (i.e. <Z.C.N>), even when the messages are arriving on different
interfaces.
This first phase of node signature support creates the signature,
incorporates it into outgoing neighbor discovery messages, and tracks
the signature used by valid neighbors. An upcoming patch builds on this
foundation to implement the improved duplicate neighbor detection checking.

This patch seeks to clean up the timer related code. It begins by
moving one-time timer setup code from tg3_open() to tg3_init_one().
It then creates a function that encapsulates the code needed to start
the timer. A tg3_timer_stop() function was added for parity. Finally,
this patch moves all the timer functions to a more suitable location.

If an error happens in the tx completion thread, tg3_reset_task will be
scheduled and TX_RECOVERY_PENDING will be set. The TX_RECOVERY_PENDING
flag causes tg3_poll[_msix] to return early before doing much of its
work. Tg3_reset_task() gets canceled when the configuration of the
device is changing, which always results in a chip reset. When this
happens, the TX_RECOVERY_PENDING flag may be left set, which would
unnecessarily hinder tg3_poll from doing work. This patch fixes the
problem.
